Web Processing Service

Discussion Paper
Description
  A Web Processing Service provides access to calculations or models which operate on spatially referenced data. The data required by the service can be available locally, or delivered across a network using data exchange standards such as GML or GDAS. The calculation can be as simple as subtracting one set of spatially referenced numbers from another (e.g. determining the difference in influenza cases between two different seasons), or as complicated as a global climate change model.

This specification is intended to provide a mechanism to identify the spatially-referenced data required by the calculation, initiate the calculation, and manage the output from the calculation so that it can be accessed by the client. The Web Processing Service is targeted at vector GIS data, not at raster image processing.
